WASHBOILER.

SPECIFICATION forming part of Letters Patent No. 498,658, dated May 30,1893.

Application filed December 31, 1892. Serial No. 456,879. (No model.)

To all whom it may concern:

Be it known that I, HENRY DELoN JEFFREY, a citizen of the United States,and a resident of Winona, in the county of Winona and State ofMinnesota,have invented certain new and useful Improvements inWash-Boilers; and I do declare the following to be a full, clear, andexact description of theinvention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is a vertical longitudinal sectionof themachine. Fig. 2 is a horizontal section on line a: m Fig. 1.

This invention has relation to certain new and useful improvements inwash-boilers,and it consists in the novel construction and combinationof parts, all as hereinafter described and pointed outin theaccompanying claim.

The object I have in view, is the provision of an improved boiler, soconstructed as to cause the generation of a jet of steam and water,which will be thrown upon the clothes or other material with sufficientforce to remove the dirt therefrom, a constant circulation being kept upwithin the boiler.

Referring to the accompanying drawings, the letter A designates aboiler, which I may construct in different forms and sizes. A shortdistance above the bottom of this boiler, is a second or false bottom B,forming a chamber or space a, and near one end of said boiler is avertical partition 0, which extends across the boiler transversely andjoins the second or false bottom at b,formingachamber c, which at itslower end communicates with the space or chamber a which forms a heatingchamber for the water. The upper portion of said chamber cis formed by ahood or spout D,

which is curved laterally, and is arranged to discharge into theinterior of the boiler. At the opposite end, the false bottom B has anopening 01 therethrough, communicating with the space or chamber a.

E represents a pipe or tube, which is shown in Figs. 1 and 2, asextending longitudinally of the bottom of the boiler and exteriorthereto, one of its ends 6 extending upwardly through the bottom andopening into the space or chamber a. The other end of said pipe has avertical arm f, which projects through the bottom into the chamber 0,and terminates in the upper portion thereof. The opening d in the falsebottom is protected by an openwork or foraminated guard F. Thisarrangement of the tubes will depend largely upon the character of thewaterin the locality in which the boiler is to be used, it being wellknown that dirt may be removed easier in soft water than in hard, sothat with the latter it is better to have a larger heating surface.

The operation is as follows:The tube E being exterior to the bottom anddirectly exposed to the fire, it will be apparent thatthe water thereinwill in a short time become heated to a sufficient degree to cause theformation of steam, and that steam and water will be discharged from theupper end of said tube and from the hood or spout D, cooler water fromthe boiler and from the space or chamber a entering the other end of thepipe. This action being continued, in a short time all the water in theboiler and in the space or chamber a will be raised to a high temperature, and steam and water will be discharged from the hood D withconsiderable force upon the contents of the boiler. I

Having thus described my-invention, what I claim as new, and desireto-secure by Letters Patent, is

A wash boiler, having a chambera between its false and true bottoms,said chamber at each end of the boiler having an opening through saidfalse bottom, a transverse vertical partition 0 near one end of saidboiler, forming a chamber 0 communicating with the chamber a through oneof said openings, a vertical transverse foraminated or openwork guard Fnear the opposite end of said boiler, and protecting the other of saidopenings, and a pipe communicating at one end with the chamber a, saidpipe extending along the bottom of the boiler exterior thereto andhaving an arm which projects upwardly into the chamber a, the upperportion of said chamber c formingacurved hood or spout through whichsaid pipe discharges into the boiler, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
